Hi and thank you 
I have an ethernet connection set up on 192.168.2.1 and can interact witht the web ui from blueos. Having enabled wifi this was initially flaky and then seem to stabilize. However when we got to the step of updating the OS, we got a message something like ““error fetching online tags” when trying to (so i understand) download a new image from docker?
Matters then got worse and we finally lost all wifi connectivity… (despite having no wifi issues from various phones and laptops) so trying to debug this as a first step.
I was following up on various posts e.g. https://discuss.bluerobotics.com/t/accessing-blueos-and-connecting-to-wi-fi/15249/3 which suggest using raspi-config to check the wifi configuration etc.
And thank you, that is likely what I am looking for i.e. terminal access from the UI window!
I see there is an advanced useage tab which allows ethernet and wifi configuration
